Description

[Technical field]

[0001] The present invention relates to a transmitter mounting structure and a disaster prevention device such as a fire hydrant device equipped with a transmitter. [Background technology]

[0002] Conventionally, disaster prevention devices equipped with disaster prevention equipment for use in emergencies such as fires, which are installed in tunnels of expressways and motorways, are known. Examples of such disaster prevention devices include fire hydrant devices and fire extinguisher boxes. For example, a fire hydrant device includes a fire hydrant storage unit having a fire hydrant door that can be opened and closed, and stores fire hydrant equipment such as a hose with a nozzle attached and valves, and a fire extinguisher storage unit having a fire extinguisher door that can be opened and closed from the front side facing the road, and further includes an electrical equipment door adjacent to the fire extinguisher door that can be opened and closed from the front side in the same way as the fire extinguisher door. In addition, the electrical equipment door is provided with electrical equipment such as a red indicator light, a transmitter, and a response lamp on the front side, and a telephone jack on the back side, and the transmitter can be operated from the front side when the electrical equipment door is closed.

[0003] Here, the fire extinguisher door and the electrical door are provided at each door opening on the front of the device, and under normal circumstances, the electrical door is temporarily fixed in the closed position by screwing a knurled screw or the like through a through hole in a receiving part provided near the door opening on the housing side opposite the mounting piece into an mounting piece with a screw hole on the back side. For example, the fire extinguisher door is held in the closed position so that it can be opened and closed by operating the door handle, etc., relative to the electrical door which is temporarily fixed in the closed position.

[0004] The transmitter also has a push button switch for transmitting signals, and the push button, which is the operating part of the push button switch, is attached to the back side of the electrical door so that it can be pressed from the front side through a specified opening provided in the electrical door, and a protective plate (safector) made of a transparent organic glass plate or the like is held on the front side of the electrical door opening at the push button position so that it can be freely attached and detached from the front side (Patent Document 1).

[0005] In the event of a fire resulting from a vehicle accident, etc., when a user presses the protective plate of the transmitter firmly from the front, the push button of the push button switch is pressed and turned on. The transmitter then sends a transmission signal to a disaster prevention receiving panel in an electrical room, etc., which outputs a fire alarm. An accompanying response signal is then sent from the disaster prevention receiving panel to the fire hydrant device, causing the response lamp to light up.

[0006] Incidentally, in such conventional transmitters, the transmitters are operated during periodic inspections to confirm that they are working properly. If the same operation as in the event of a fire is performed during the inspection of the transmitter, it is necessary to fit the protective plate back into the opening to return it to its original state after the inspection is completed. In Patent Document 1, the protective plate is pressed from the front side and falls into the space between the front panel of the electrical door and the push button, and the operation of returning the protective plate to its normal position requires a special tool and is time-consuming. Alternatively, if the protective plate is a destructive seal plate, it is necessary to replace the protective plate with a new one, which is also time-consuming.

[0007] This means that inspecting transmitters is time-consuming and labor-intensive, and in tunnel facilities and the like, a large number of transmitters installed at regular intervals must be inspected sequentially, resulting in poor inspection efficiency.

[0008] In order to solve this problem, in Patent Document 2, as shown in Figures 1, 2, and 4 of Patent Document 2, a protective plate is provided on the outer door side, an inner door with a push button switch attached is provided on the back side of the outer door, and the push button of the push button switch is located on the front side of the inner door. In this way, by opening only the outer door during inspection, it is possible to operate the push button without pressing the protective plate, that is, while keeping the protective plate in the normal state, which makes it easier to inspect the transmitter and improves the efficiency of the inspection work.

[0009] In Patent Document 2, as shown in Figures 5 to 7, an inner sub-door is provided on the back side of the reporting device door (electrical door), a push button switch of the transmitter is attached to the inner sub-door, and the inner sub-door is configured to rotate about an axis in the vertical direction when the device is installed and open in the width direction of the device (horizontal direction when installed). In this way, during inspection, the inner sub-door is opened with the electrical door open, exposing the push button of the push button switch to the outside, and enabling the push button to be operated while the protective plate is maintained in the normal state, making inspection of the transmitter easier and improving the efficiency of the inspection work. [Prior art documents] [Patent documents]

[0010] [Patent Document 1] JP 2011-060580 A [Patent Document 2] JP 2016-018219 A Summary of the Invention [Problem to be solved by the invention]

[0011] However, in the configuration of Patent Document 2, the outer door can be opened relatively easily from the front side, which increases the possibility that not only professional inspectors but also general users will open the outer door unnecessarily, which is undesirable.

[0012] In addition, in the configuration shown in Figures 1, 2 and 4 of Patent Document 2 in which an inner door with a push button switch attached to the back side of the outer door is provided, the inner door is fixed to the opening of the housing by screw fastening or the like, and although it is called an inner door, it is a fixed plate that does not have an opening and closing structure with a hinge like the outer door, and when performing work such as repairing or replacing the push button switch of the transmitter attached to the inner door, it is necessary to remove the inner door, which makes the repair or replacement time-consuming and laborious.

[0013] Furthermore, with regard to the configuration in which an inner sub-door is provided on the back side of the reporting device door (electrical door) shown in Figures 5 to 7 of Patent Document 2, if the inner sub-door is opened to complete inspection of the push button switch and then forgotten to be fixed in a completely closed position, it may be difficult to check the state from the front side, leaving room for further improvement.

[0014] The present invention aims to solve the above-mentioned problems in Patent Document 2 and to provide a transmitter mounting structure and a disaster prevention device equipped with a transmitter that can further facilitate inspection and repair / replacement work of transmitters, thereby improving work efficiency. [Means for solving the problem]

[0015] (Transmitter mounting structure) The present invention provides a transmitter mounting structure for mounting a transmitter on an external door that is provided in a predetermined door opening formed in a predetermined device and can be opened and closed, the transmitter being configured to operate a push button of a push button switch located on the back side of a protective plate by pressing the protective plate that is detachably held in an operation opening formed in the external door, the structure comprising: The device is characterized in that an internal door, on which a push button switch is attached so that an operating part is located at the front, is provided inside the external door so as to be freely opened and closed, and a door opening and closing structure is provided for opening the external door while the internal door is fixed closed to expose the push button of the push button switch attached to the internal door so as to be operable.

[0016] (Door opening and closing structure) The door opening and closing structure is A hinge structure that supports the outer door and the inner door on a common axis so that they can be opened and closed freely at the door opening, A first opening / closing operation unit that operates to close and release the internal door; A second opening / closing operation unit that has higher operability than the first opening / closing operation unit and operates to close and release the external door; Equipped with With the internal door fixed closed by the first opening / closing operation unit, the external door is released from the closed state by the second opening / closing operation unit and opened, thereby exposing the operation unit of the push button switch attached to the internal door so that it can be operated.

[0017] (Hinge structure) The hinge structure is A first hinge that pivotally supports the inner door to the door opening so that it can be opened and closed freely, and a second hinge that pivotally supports the outer door to the door opening so that it can be opened and closed freely are pivotally supported by the same shaft so that they can rotate freely.

[0018] (1st opening / closing operation part) The first opening / closing operation section is provided on the rear surface side of the inner door and performs a fastening operation and a fastening release operation of the inner door by a screw member that can be operated by a fingertip.

[0019] (Screw member of first opening / closing operation part) The fingertip operable screw member includes a knurled screw or a thumb screw.

[0020] (Second opening / closing operation part 1) The second opening / closing operation portion is provided on the side edge of the tip side of the exterior door or on the inside of the side edge, and is fixed to and released from the door opening by movement of the rod member accompanying operation of the door handle.

[0021] (Second opening / closing operation part 2) The second opening / closing operation unit is a socket portion disposed in the door opening with the socket hole facing the rear side; A plug member disposed on the rear surface side of the exterior door opposite the socket portion; It is composed of With the outer door closed, the plug is pushed in to be fixed to the socket, and the plug is released from the socket by being pushed in again after the previous pushing operation.

[0022] (Electrical Equipment) The internal door is fitted with a transmitter push button switch, as well as a display device and a telephone jack, and other electrical equipment. A display window or display opening is formed in the outer door corresponding to the display device.

[0023] (Disaster Prevention Devices) In another aspect of the present invention, an external door provided at a predetermined door opening formed on the front surface of the device and having a transmitter as a predetermined electrical device; an apparatus door that is provided at a predetermined door opening formed on a front surface of the apparatus and that is opened when accessing the inside of the apparatus; A disaster prevention device comprising: The transmitter is attached to the inner door by the transmitter mounting structure described above. The door opening structure of the transmitter mounting structure can be accessed through the door opening opened by opening the device door. Effect of the Invention

[0024] (Effect of transmitter mounting structure) The present invention provides a transmitter mounting structure in which an external door is provided so as to be freely opened and closed in a specified door opening formed in a specified device, and a transmitter is attached to the external door, in which a push button of a push button switch located on the back side of a protective plate is operated by pressing a protective plate that is held in a removably manner in an operation opening formed in the external door. An internal door, on the inside of the external door, is provided so as to be freely opened and closed, with a push button switch attached so that the push button is located on the front side. The present invention provides a transmitter mounting structure in which a transmitter is mounted to an external door that is freely opened and closed, and a transmitter is mounted to an internal door that is freely opened and closed, and a transmitter opening and closing structure is provided in which the external door is opened while the internal door is closed and fixed, to expose and operate the operation unit of the push button switch attached to the internal door. Therefore, when the operation unit of the push button switch of the transmitter can be directly turned on, the external door is opened to expose the operation unit of the push button switch attached to the internal door to the outside, making the operation easy, making inspection of the transmitter simple and easy, and enabling the efficiency of the inspection work to be improved.

[0025] (Effect of door opening and closing structure) In addition, the door opening and closing structure comprises a hinge structure that supports the external door and internal door on the door opening by a common axis so that they can be opened and closed freely, a first opening and closing operation unit that operates to fix the internal door closed and release said fixed closed, and a second opening and closing operation unit that has higher operability than the first opening and closing operation unit and operates to fix the external door closed and release said fixed closed.When the internal door is fixed closed by the first opening and closing operation unit, the external door is released and opened by the second opening and closing operation unit, exposing the operation unit of the push button switch attached to the internal door so that it can be operated.Since the hinges of the external and internal doors are shared, it is possible to support a double-layered door on the door opening so that it can be opened and closed freely in the minimum space required, and it is also possible to make the double-layered door thinner.

[0026] In addition, by providing a first opening / closing operation unit for opening and closing the internal door and a second opening / closing operation unit for opening and closing the external door separately, when inspecting the transmitter, the second opening / closing operation unit can be used to release the closed lock of the external door, making the inspection work of the transmitter simple and easy; on the other hand, when repair or replacement of the push button switch is required, the first opening / closing operation unit can be used to release the closed lock of the internal door, making the repair or replacement work of the transmitter simple and easy.

[0027] In addition, the second opening / closing operation part of the outer door is designed to be easier to operate than the first opening / closing operation part of the inner door. For example, during regular inspection of the transmitter, the outer door can be opened by a single touch of the second opening / closing operation part. On the other hand, the first opening / closing operation part of the inner door is designed to be less easy to operate, for example by being fixed with a screw, so that it is securely closed and fixed under normal circumstances, but when performing infrequent work such as repairing or replacing electrical equipment such as transmitters, the lock can be released relatively easily and without using tools to open the inner door.

[0028] (Effect of hinge structure) In addition, the hinge structure is such that the first hinge, which supports the inner door on the door opening so that it can be opened and closed freely, and the second hinge, which supports the outer door on the door opening so that it can be opened and closed freely, are supported by the same axis so that they can rotate freely.This makes it possible to close and fix the outer door and inner door in a stacked position one behind the other, and also makes it possible to open and close the outer door individually, to open and close the inner door individually with the outer door open, and even to open and close the outer door and inner door together.

[0029] (Effect of the first opening / closing operation part) In addition, the first opening / closing operation unit is provided on the back side of the internal door, and the internal door is fixed and unlocked by a screw member that can be operated with fingertips, so that even if the external door is opened, the first opening / closing operation unit is provided on the back side of the internal door, so that unwanted opening by general users can be prevented, and even if the location of the first opening / closing operation unit is known, the structure has low operability due to the screw member that can be operated with fingertips, so that unwanted opening by general users can be reliably prevented. On the other hand, inspectors and other related parties know the location of the first opening / closing operation unit and have knowledge of fixing the door with a screw member that can be operated with fingertips, so that they can release the closed fixation of the internal door as necessary and easily open it.

[0030] (Effect of the screw member of the first opening / closing operation part) In addition, since the screw member that can be operated with the fingertips includes a knurled screw or a thumb screw, a person performing the necessary work can simply and easily close or release the internal door by turning the knurled screw or thumb screw with their fingertips without using tools, even when wearing gloves.

[0031] (Effect of second opening / closing operation unit 1) In addition, the second opening / closing operation part of the external door is provided on the side edge or inside of the side edge at the tip of the external door, and is designed to be fixed and unlocked from the door opening by the movement of a rod member arranged in the vertical direction in response to the operation of the door handle.Since the second opening / closing operation part is located in a position that is difficult to see from the front, such as the side edge or inside of the side edge at the tip of the external door, it is possible to prevent unnecessary opening by general users.On the other hand, since inspectors and other relevant parties know the position of the first opening / closing operation part, they can release the closed lock of the external door and easily open it.

[0032] In addition, the second opening / closing operation part of the external door retracts a rod member when the door handle is pulled, releasing the closed lock, and by returning the pulled door handle with the external door closed, the rod member returns to lock the door closed. This single-touch operation of the door handle provides high operability and makes closing and unlocking the external door simple and easy.

[0033] (Effect of second opening / closing operation unit 2) In addition, as another configuration, the second opening / closing operation part of the external door is composed of a socket part that is arranged in the door opening with the socket hole facing the back side, and a plug member that is arranged on the back side of the external door opposite the socket part, and is fixed to the socket part by pushing the plug in when the external door is closed, and is released from the socket by pushing the plug again after the pushing operation. Therefore, a known cam lock fastener, for example, can be used as the second opening / closing operation part of the external door, and the operations of closing and releasing the external door to the door opening are performed by one-touch operation of the plug part provided on the back side of the external door, resulting in high operability and making the closing and releasing of the external door simple and easy.

[0034] In addition, the second opening / closing operation part is located in a position that is difficult to see from the side end or the front inside of the side end of the exterior door, thereby preventing unnecessary opening by general users. On the other hand, inspectors and other relevant parties know the location of the second opening / closing operation part, so they can release the closed lock of the exterior door and easily open it.

[0035] (Effect of display device) In addition, the inner door is fitted with electrical equipment including a transmitter push button switch, a display device and a telephone jack, and a display window or opening is formed in the outer door corresponding to the display device, so that by releasing the inner door from its closed state and opening it, inspection, replacement and repair of the electrical equipment attached to the inner door can be easily and simply performed.

[0036] (Disaster Prevention Devices) In another embodiment of the present invention, a disaster prevention device is provided with an external door provided in a predetermined door opening formed on the front of the device and having a transmitter provided as a predetermined electrical device, and an apparatus door provided in the predetermined door opening formed on the front of the device and opened when accessing the inside of the device, in which the transmitter is attached to the internal door by the above-mentioned transmitter mounting structure, and the door opening and closing structure of the transmitter mounting structure can be accessed from the door opening opened by opening the apparatus door. Therefore, since the internal door of a fire hydrant device, which is a type of disaster prevention device, is provided with a telephone jack in addition to the transmitter push button switch, and the fire extinguisher door, which corresponds to the apparatus door, must be opened during inspection in order to connect a handset to the telephone jack to make a call, in a fire hydrant device to which a transmitter mounting structure is applied that allows the external door to be opened and the push button switch of the transmitter attached to the internal door to be inspected, the fire extinguisher door is not opened just to inspect the transmitter, and the external door can be opened to press the operating part of the push button switch attached to the internal door, making it possible to simply and easily inspect the transmitter while holding the handset.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0038] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a transmitter mounting structure and a disaster prevention device including a transmitter according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the following embodiment.

[0039] [Basic Concept of the Embodiment] First, a basic concept of the embodiment will be described. The embodiment generally relates to a disaster prevention device provided with a transmitter mounting structure for mounting a transmitter on an external door and an external door to which the transmitter is mounted by the transmitter mounting structure.

[0040] Here, the "external door" is a door opening of a specific device such as a disaster prevention device that can be opened and closed, and the transmitter mounting structure is for mounting a transmitter in which a push button of a push button switch located on the back side of a protective plate is operated by pushing in a protective plate that is detachably held in an operation opening formed in the external door. Note that the "external door" includes the concepts of an "outer door" and an "exterior door."

[0041] The "transmitter" is operated by pushing in a protective plate that is removably held in an operation opening formed in the external door, and when the transmitter is activated, it transmits, for example, a transmission signal. Therefore, the "transmitter" is confirmed to be operating normally by operating the operation part of the push button switch during inspection. Note that the "front side" refers to the outside of the device when an external door is provided in the door opening of the device, and the "rear side" refers to the inside of the device.

[0042] The mounting structure for the transmitter in the embodiment is characterized in that an internal door with a push button switch attached to it is provided on the inside of the external door so that the operating part is located at the front and can be opened and closed freely, and a door opening and closing structure is provided which, when the internal door is closed and fixed, opens the external door to expose and operate the operating part of the push button switch attached to the internal door.As a result, when the operating part of the push button switch of the transmitter must be directly turned on during inspection, for example, the external door is opened to expose the operating part of the push button switch attached to the internal door to the outside, facilitating said operation, making inspection of the transmitter simple and easy and enabling the efficiency of the inspection work to be improved.

[0043] The "door opening and closing structure" is a structure that opens and closes a double door consisting of an outer door and an inner door, and the structure and mechanism are arbitrary, but it may be composed of, for example, a hinge structure, a first opening and closing operation part for the inner door, and a second opening and closing operation part for the outer door. Note that the term "inner door" includes the concepts of an "inner door" and an "internal door."

[0044] Here, the "hinge structure" refers to a structure in which an outer door and an inner door are pivotally supported on a door opening by a common shaft so that they can be opened and closed freely. The structure and function are arbitrary, but for example, a first hinge that pivotally supports the inner door on the door opening so that it can be opened and closed freely, and a second hinge that pivotally supports the outer door on the door opening so that it can be opened and closed freely are pivotally supported on the same shaft so that they can be rotated freely. Normally, a well-known "three-tube hinge" is used as a hinge used to open and close a door, but in this embodiment, a so-called "double three-tube hinge" that has a structure in which two well-known three-tube hinges are connected in the axial direction is used as the first hinge and the second hinge. Note that "hinge" includes the concepts of "hinge" and "hinge".

[0045] In addition, the "first opening / closing operation unit" is used to operate the closing and fixing of the internal door and to release said closing and fixing. Since the opening and closing of the internal door is intended for infrequent work such as repairing and replacing electrical equipment installed such as transmitters, it does not require high operability like the second opening / closing operation unit of the external door.

[0046] The function and structure of the "first opening / closing operation part of the internal door" are arbitrary, but since high operability is not required, for example, it is provided on the back side of the internal door, and the internal door is fixed and unlocked by a screw member that can be operated with fingertips. Here, the type and structure of the "fingertip-operable screw member" are arbitrary, but it includes, for example, a knurled screw or a thumb screw. This makes it easy and simple for a person who opens the internal door to perform necessary work to close or unlock the internal door by turning the knurled screw or thumb screw with their fingertips without using tools, even when wearing gloves.

[0047] Even if the exterior door is opened, the first opening / closing operation part is provided on the back side of the interior door, so unwanted opening by general users can be prevented, and even if the location of the first opening / closing operation part is known, the structure has low operability due to the screw member that can be operated with fingertips, so unwanted opening by general users can be reliably prevented. On the other hand, inspectors and other related parties know the location of the first opening / closing operation part and have knowledge of fixing the door with the screw member that can be operated with fingertips, so they can release the closed fixation of the interior door as necessary and easily open it.

[0048] The "second opening and closing operation part of the external door" has higher operability than the first opening and closing operation part of the internal door, and allows the external door to be easily closed and released. The structure and function of the "second opening and closing operation part of the external door" are arbitrary, but since it has higher operability than the first opening and closing operation part of the internal door, it is provided, for example, on the side edge or inside of the side edge of the tip side of the external door, and the door opening is fixed and released by the movement of a rod member arranged in the vertical direction in response to the operation of the door handle.

[0049] As a result, the second opening / closing operation part is located in a position that is difficult to see from the front, such as the side edge or inside side edge of the tip side of the external door, preventing unnecessary opening by general users, while inspectors and other related parties know the location of the second opening / closing operation part and can easily release the external door from the closed state and open it easily. Also, the second opening / closing operation part of the external door is highly operable since it can be closed and released with a single touch of the door handle. Here, "the side edge on the tip side of the external door" means the side edge of the door when the hinge side of the external door is considered to be the rear end and the opposite side of the door is considered to be the tip.

[0050] Another configuration of the "second opening / closing operation part of the external door" with high operability is, for example, a socket part arranged in the door opening with the socket hole facing the back side, and a plug member arranged on the back side of the external door opposite the socket part, which is fixed to the socket part by pushing the plug when the external door is closed, and is released from the socket by pushing the plug again after the pushing operation. For this purpose, for example, a known cam lock fastener can be used as the "second opening / closing operation part of the external door", and high operability is obtained because the operations of closing and releasing the external door to the door opening are performed by one-touch operation of the plug part provided on the back side of the external door.

[0051] In addition to the push button switch for the transmitter, electrical equipment including a display device and a telephone jack is attached to the "internal door," and a display window or display opening is formed in the external door corresponding to the display device. Therefore, by releasing the closed fixation of the internal door with the first opening / closing operation unit and opening it, inspection, replacement, repair, etc. of the electrical equipment attached to the internal door can be made simple and easy.

[0052] Furthermore, a disaster prevention device that has an external door and an internal door to which a transmitter is attached using the transmitter mounting structure includes any device, equipment, etc. in which a transmitter is installed, such as a fire hydrant device, a fire extinguisher box, an emergency notification device, etc.

[0053] Here, a "fire hydrant device" is a device that is installed in an area to be extinguished, such as a tunnel on a highway or a road for automobiles, and has a fire hydrant device such as a fire hose stored inside, an "emergency notification device" is a device that is equipped with necessary electrical equipment such as a red indicator light and a response lamp in addition to a transmitter, and a "fire extinguisher box" is a device that has a fire extinguisher stored inside. In addition, a "fire hydrant device" includes a device that is installed together with an "emergency notification device" or a "fire extinguisher box," and a "fire extinguisher box" includes a device that is installed together with an "emergency notification device." In addition, in the case of a fire hydrant device, the "external door" is sometimes called an "electrical door."

[0054] In addition, the "disaster prevention device" is equipped with a double-layered external door and internal door that are installed in a designated door opening formed on the front of the device and in which a transmitter is installed as a designated electrical device, and an equipment door that is installed in a designated door opening formed on the front of the device and is opened when accessing the inside of the device, and the external door can be opened through the door opening opened by opening the equipment door, making it possible to access the transmitter mounting structure for inspecting the transmitter attached to the internal door.

[0055] In addition, the "apparatus door" refers to a door that is opened when accessing the inside of the apparatus, for example, when using a fire hydrant or a fire extinguisher stored inside, and in a conventional fire extinguisher box as shown in Figures 5 to 7 of Patent Document 2, the fire extinguisher door adjacent to the electrical door corresponds to the apparatus door. Note that the door opening in which the electrical board is provided and the door opening in which the apparatus door is provided may be the same door opening or may be different door openings.

[0056] In the following, specific embodiments will be described. In the embodiment, the "disaster prevention device" is a "fire hydrant device in which a fire extinguisher box and an emergency notification device are integrated", the "external door" is an "electrical door", the "device door" is a "fire extinguisher door", the "transmitter inspection structure" is "one that has an electrical door, an internal door, and an opening and closing structure", the "door opening and closing structure" is "one that has a hinge structure, a first opening and closing operation part for the internal door, and a second opening and closing operation part for the external door", the "first opening and closing operation part for the internal door" is "one that fixes the internal door closed and releases the closed fixation by a thumbscrew or a knurled screw", and the "second opening and closing operation part for the external door" is "one that moves a rod member by operating a door handle" or "one that fixes the external door closed and releases the closed fixation by pushing a plug into a socket".

[0064] The red indicator light 22 is always on, allowing the location of the fire hydrant device 10 to be known from a distance. In addition, in the event of a fire, a user presses the protective plate of the transmitter 24 to turn on the push button switch of the transmitter 24, which sends a fire notification signal (transmission signal) from the transmitter 24 to a disaster prevention receiving panel in an electrical room or the like, which outputs a fire alarm, and in response, a response signal is sent from the disaster prevention receiving panel to the fire hydrant device 10, causing the red indicator light 22 to flash and the response lamp 26 to light up.

[0065] [b. Structure of the casing on the fire extinguisher storage side] Next, the structure of the housing on the fire extinguisher storage side will be explained. In this explanation, reference will be made to Fig. 2, which shows the cross section of the fire extinguisher storage section in plan (top), and Fig. 3, which shows the decorative frame equipped with the double door (electrical door and internal door) and the fire extinguisher door from the back side. Note that Fig. 2 shows the cross section along the aa cutting line in Fig. 1.

[0066] As shown in Fig. 2, two fire extinguishers 30 are stored in a fire extinguisher storage section inside the housing 11b, and terminal boxes 21a, 21b are provided on the inside rear surface of the housing 11b. The red indicator light 22 shown in Fig. 3 is connected to the terminal box 21a via a wiring cable, and the transmitter 24, response lamp 26, telephone jack 28, and a pump start switch and pump start interlock switch provided in the fire hydrant storage section of the housing 11a are connected to the terminal box 21b via wiring cables.

[0067] As shown in Fig. 3, a waterproof rubber seal 17 is provided around the door opening 15 of the decorative frame 11b. As shown in Figs. 2 and 3, a fire extinguisher door 18 that opens sideways to the left by a hinge 18a is provided on the left side of the door opening 15 of the decorative frame 11b, and an electrical door 20 and an internal door 32 are provided as double doors on the right side of the door opening 13 of the decorative frame 11b. The electrical door 20 and the internal door 32 that constitute the double doors are pivoted so as to open sideways to the right individually by a double three-pipe hinge 34 having a structure in which two hinges with a common axis are connected together.

[0068] The fire extinguisher door 18 and the electrical door 20 are provided in the door opening 13 of the decorative frame 11b as double-hinged doors that open in opposite directions via hinges 18a and double three-pipe hinges 34, and the joint between the fire extinguisher door 18 and the electrical door 20 is formed as opposing stepped portions, and when the doors are in the closed position, the stepped portion of the electrical door 20 is located inside the door opening 15, and the stepped portion of the electrical door 20 is located outside (front) the door opening 15.

[0069] [c. Structure of the internal door and electrical door] Next, the structures of the internal door 32 and the electrical door 20 will be described. In this description, in addition to Fig. 3, reference will be made to Fig. 4, which shows a cross-section of the mating surface with the fire extinguisher door from the left side in a state where the electrical door and the internal door are closed and fixed and in a state where the electrical door is open, Fig. 5, which shows a state where the internal door is opened following the electrical door, similar to Fig. 4, and Fig. 6, which shows the fire hydrant device from the front in a state where the fire extinguisher door and the electrical door are open to expose the internal door.

[0070] As shown in Figures 3 and 4, the internal door 32 located on the back side of the electrical door 20 is equipped with, from top to bottom, a red indicator light 22, a push button switch 2410 of the transmitter 24, a telephone jack 28, and an answer lamp 26.

[0071] Of these, the push button switch 2410 of the transmitter 24 is attached so that a switch knob 2430 serving as an operation unit is located on the front surface of the internal door 32. In the operation opening on the door surface of the electrical door 20 facing the switch knob 2430 of the push button switch 2410 attached to the internal door 32, a protective plate 25a is arranged by a protective plate storage section 25 so as to be freely pushed in, as shown in FIG.

[0072] In addition, display openings 22a, 26a are formed on the door surface of the electrical door 20 facing the red indicator light 22 and the response lamp 26 attached to the internal door 32, making the red indicator light 22 and the response lamp 26 visible from the front.

[0073] Normally, as shown in Fig. 4(A), the internal door 32 and the electrical door 20 are closed in the closed position, the internal door 32 is fixed closed by the first opening / closing operation part 36, and the electrical door 20 is fixed closed by the second opening / closing operation part 38. Note that normally, as shown in Figs. 1 and 2, the fire extinguisher door 18 is also fixed closed with the electrical door 20 fixed closed facing the door frame.

[0074] When inspecting the transmitter 24, the electrical equipment door 20 is released from its closed state by the second opening / closing operation unit 38, and the electrical equipment door 20 is opened as shown in Fig. 4(B) and Fig. 6. When the electrical equipment door 20 is opened, the switch knob 2430 of the push button switch 2410 attached to the internal door 32 is exposed to the front (outside), and the switch knob 2430 can be directly pressed to turn it on, allowing inspection of the transmitter 24.

[0075] In addition, when inspecting, repairing or replacing electrical equipment including the transmitter 24 attached to the internal door 32 if the electrical equipment breaks down, the internal door 32 is released from its closed position by the first opening / closing operation unit 36, and the internal door 32 is opened as shown in FIG. 5, making it possible to carry out work such as repairing or replacing the push button switch 2410 of the transmitter 24.

[0076] [d. Hinge structure] Next, the hinge structure of the double door consisting of the electrical door 20 and the internal door 32 will be described. In this description, reference will be made to Fig. 7, which shows a cross section of the electrical door and the internal door when they are closed and fixed, Fig. 8, which shows the double three-tube hinge that supports the electrical door and the internal door so that they can be opened and closed, Fig. 9, which shows a cross section of the electrical door when it is open, and Fig. 10, which shows a cross section of the internal door and the electrical door when it is open. Note that Fig. 7 shows a cross section along the cutting line cc in Fig. 4(A), and Fig. 8 shows a cross section along the cutting line dd in Fig. 4(B). Also, Fig. 8(A) shows the double three-tube hinge when it is open, and Fig. 8(B) shows a cross section along the cutting line ee in Fig. 8(A).

[0077] As shown in FIG. 7, a double three-tube hinge 34 is provided as a hinge structure for pivotally supporting the electrical door 20 and the internal door 32 so that they can be opened and closed freely.

[0078] 8(A), the double three-pipe hinge 34 comprises a first hinge 3410 and a second hinge 3420. The first hinge 3410 is integrally provided with a pair of bearing pipes 3416, 3417 formed into a tubular shape by dividing them in the axial direction at the side end of the door mounting plate portion 3412, and also integrally provided with a bearing piping portion 3418 on the upper side of the base mounting portion 3430.

[0079] The second hinge 3420 is similar to the first hinge 3410, and has a pair of bearing tube sections 3426, 3427 formed into a tubular shape by dividing them in the axial direction integrally with the side end of the door mounting plate section 3422, and also has a bearing piping section 3428 integrally with the underside of the base mounting section 3430.

[0080] The three bearing tubes 3416, 3417, 3418 of the first hinge 3410 and the three bearing tubes 3426, 3427, 3428 of the second hinge 3420 are coaxially arranged and are supported by a shaft 3440 therethrough for free rotation.

[0081] The base mounting part 3430 has a stepped plate structure bent in multiple stages to support and fix the hinge to the decorative frame 11b on the base side. The door mounting plate parts 3412, 3422 and the base mounting part 3430 have through holes 40 used for screw fixing formed in multiple places. Note that a known hinge, for example, has the first hinge 3410 as an independent hinge and has three bearing tube parts 3416, 3417, 3418, and is therefore called a "three-tube hinge."

[0082] Next, a pivot structure for allowing the electrical door 20 and the internal door 32 to be opened and closed freely by the double three-tube hinge 34 will be described. As shown in FIG. 7, the base fixing part 3430 of the double three-tube hinge 34 is screwed and fixed to the inner protruding part 11c of the decorative frame 11b on the housing side, and the axis part 3440 is supported at a predetermined position on the right end of the door opening 15. The door mounting plate part 3412 of the first hinge 3410 pivotally supported by the axis part 3440 is screwed and fixed to the right end of the internal door 32, supporting the internal door 32 so as to be freely opened sideways to the right. In addition, the door mounting plate part 3422 of the second hinge 3420 pivotally supported by the axis part 3440 is screwed and fixed to the inside of the right end of the electrical door 20, supporting the electrical door 20 so as to be freely opened sideways to the right.

[0083] This hinge structure allows the electrical door 20 to be opened and closed with the internal door 32 fixed closed during inspection, etc., as shown in Fig. 9, provided that the fire extinguisher door 18 is open. In addition, as shown in Fig. 10, the internal door 32 can be opened and closed during repair or replacement of electrical equipment such as a transmitter, provided that the electrical door 20 is open, and further allows the electrical door 20 and the internal door 32 to be opened and closed together.

[0084] [e. Structure of the first opening / closing operation part of the inner door] Next, the structure of the first opening / closing operation portion 36 of the inner door 32 will be described with reference to Figs.

[0085] 3, the internal door 32 is provided with a first opening / closing operation unit 36, and the internal door 32 is fixed closed or released by operating the first opening / closing operation unit 36. The first opening / closing operation unit 36 ​​is provided on the back side of the internal door 32 which can be accessed and operated from the door opening when the fire extinguisher door 18 is opened, and makes it possible to prevent unnecessary opening by general users.

[0086] The first opening / closing operation part 36 has a structure that allows the door to be fixed in place and released from its closed state by fingertip operation, and while its structure and function are arbitrary, it is, for example, composed of a thumbscrew 3610 and an attachment piece 3620. The attachment piece 3620 is fixed to predetermined positions above and below the back side of the door opening 15 where the inner door 32 is located, and has a through hole formed therein.

[0087] A screw hole is formed in the door surface of the internal door 32 facing the through hole of the mounting piece 3620, and a thumb screw 3610 is passed through the through hole of the mounting piece 3620 and screwed into the screw hole in the door surface, thereby closing and fixing the internal door 32 to the door opening 15 of the decorative frame 11b. Also, by opening the fire extinguisher door 18 and reaching a hand into the back surface of the internal door 32 from the door opening 15, the thumb screw 3610 can be removed from the screw hole in the door surface, thereby releasing the closed fixing of the internal door 32 and allowing it to be opened. Note that a knurled screw may be used instead of the thumb screw 3610.

[0088] [f. Structure of the second opening / closing operation part of the electric door] Next, the structure of the second opening / closing operation part 38 of the electrical door 20 will be described. In this description, in addition to Fig. 3 to Fig. 5, Fig. 11 showing the second opening / closing operation part of the electrical door 20 that moves a rod by a door handle will be referred to. Fig. 11(A) shows the electrical door in a closed and fixed state, and Fig. 11(B) shows the electrical door in a released state.

[0089] 3 to 5, the electrical door 20 is provided with a second opening / closing operation unit 38, and the electrical door 20 is fixed closed or released by operating the second opening / closing operation unit 38. The second opening / closing operation unit 38 is provided in a difficult-to-see position on the side opposite the hinge of the electrical door 20 or on the back side of the side, making it possible to prevent unnecessary opening by general users.

[0090] Here, the second opening / closing operation part 38 of the electrical door 20 is structured to have higher operability than the first opening / closing operation part 36 of the internal door 32. This is because the opening and closing operation of the internal door 32 is required for work that occurs infrequently, such as repairing or replacing the installed electrical equipment, and the internal door 32 is structured mainly for temporary fixing so that it will not normally be opened. On the other hand, the opening and closing operation of the electrical door 20 is required for work that occurs frequently, such as the periodic inspection work of the transmitter 24, and therefore is structured to have high operability so that it can be easily operated.

[0091] As shown in Figure 11 (A), the second opening / closing operation part 38 of the electrical door 20 has a door handle 3810 disposed approximately in the center in the vertical direction of the side end of the electrical door 20, and a rod 3830 extends upward from the door handle 3810, and a rod 3840 extends downward.

[0092] The upper end of the rod 3830 extended upward passes through a guide hole 44 formed in the upper edge of the electrical door 20 and through a through hole 42 formed in the inner edge of the door opening 15 of the decorative frame 11b, thereby fixing the upper side of the electrical door 20 closed against the housing side.

[0093] In addition, the lower end of the rod 3840 extended downward passes through a guide hole 44 formed in the lower edge of the electrical door 20 and through a through hole 42 formed in the inner edge of the door opening 15 of the decorative frame 11b, thereby closing and fixing the lower side of the electrical door 20 to the housing side.

[0094] The door handle 3810 connects the rods 3830, 3840 by a known link mechanism, and as shown in FIG. 11(B), when the lever 3820 of the door handle 3810 is pulled toward the user, the rods 3830, 3840 are pulled toward the door handle 3810 and come out of the through holes 42 of the decorative frame 11b, thereby releasing the closed lock of the electrical door 20.

[0095] Furthermore, when the lever 3820 is released and returned to its original position with the electrical equipment door 20 in the closed position, the rods 3830 and 3840 are pushed out and pass through the through holes 42 of the decorative frame 11b, and the electrical equipment door 20 is fixed closed.

[0096] [g. Other embodiments of the second opening / closing operation part of the electric door] Next, another embodiment of the second opening / closing operation part of the electrical door will be described. In this description, reference will be made to Fig. 12, which shows the second opening / closing operation part of the electrical door using a lock fastener. Fig. 12(A) shows the electrical door in a closed and fixed state, and Fig. 12(B) shows the electrical door in a released state.

[0097] As shown in Figure 12 (A), the second opening / closing operation part 46 of the electrical door 32 in another embodiment is arranged on the inside of the side end opposite the hinge side of the electrical door 20 in a position that is difficult to see from the front, as in the case of Figure 11, thereby making it possible to prevent unnecessary opening by general users.

[0098] The second opening / closing operation portion 46 of this embodiment, like the structure in FIG. 11, is for fixing the electrical equipment door 20 closed and releasing the fixed closed state, and uses a known cam lock fastener.

[0099] 12(A), the second opening / closing operation section 46 of the electrical door 20 using a cam lock fastener is provided at two positions, one above and one below, of the electrical door 20, and is composed of a socket 4610 and a plug 4620. The socket 4610 is fixed to a through hole formed in a partition wall 2010 on the back side of the electrical door 20, and the plug 4620 is fixed to a mounting piece 48 fixed to the inside of the decorative frame 11b opposite the socket 4610.

[0100] When the electrical equipment door 20 is held in the closed position as shown in FIG. 12(A) and the plug 46200 is pushed into the socket 4610 in this state, the plug 4620 is fixed to the socket 46100 and prevented from coming out by the operation of a known cam lock mechanism.

[0101] When the plug 4620 is pressed in while it is fixed to the socket 4610, the plug 4620 is released from the lock by the operation of a known cam lock mechanism, allowing the electrical equipment door 20 to be opened as shown in FIG. 12(B).

[0102] By providing the second opening / closing operation part 46 of the electrical door 20 composed of the socket 4610 and the plug 4620 in this manner, it is possible to simply close and release the electrical door 20 with a single touch of pushing in the plug 4620.

[0103] [h. Transmitter inspection work] Next, the inspection work of the transmitter will be described below. In this description, the case where the second opening / closing operation part 38 of the electrical equipment door 20 shown in FIG. 11 is provided will be described as an example.

[0104] When an inspector inspects the transmitter 24 installed on the electrical door 20 of the fire hydrant device 10 during inspection, the inspector opens the fire extinguisher door 18 shown in Figures 1 and 2, inserts his / her hand wearing work gloves onto the back side of the electrical door 20 from the portion of the door opening 15 shown in Figure 3 that has been opened by opening the fire extinguisher door 18, and pulls the lever 3820 of the door handle 3810 as shown in Figure 11 (B). This causes the rods 3830, 3840 arranged above and below to be retracted, and the electrical door 20 is released from its closed position.

[0105] 4(B), 6 and 9, the electrical door 20 is opened relative to the internal door 32 which is fixed closed, and the switch knob 2430 of the push button switch 2410 constituting the transmitter 24 attached to the internal door 32 is exposed forward (outside). Next, the inspector operates the switch knob 2430 of the exposed push button switch 2410 to transmit a transmission signal from the transmitter 24 to the disaster prevention receiving panel and checks whether it operates normally.

[0106] After completing inspection of the transmitter 24, as shown in FIG. 11(B), the lever 3820 of the door handle 3810 is pulled to retract the rods 3830, 3840, and the electrical door 20 is returned to the closed position. When the lever 3820 is released, the rods 3830, 3840 are pushed up and down, and the door is fixed in the closed position.

[0107] [i. Inspection and repair of electrical equipment] Next, the inspection and repair work of the electrical equipment attached to the internal door 32 will be described using the transmitter 24 as an example.

[0108] If a malfunction or other problem occurs in the push button switch 2410 that constitutes the transmitter 24, the person in charge opens the fire extinguisher door 18 shown in Figures 1 and 2, inserts his / her hand wearing work gloves onto the back side of the electrical door 20 through the portion of the door opening 15 shown in Figure 3 that has been opened by opening the fire extinguisher door 18, and pulls the lever 3820 of the door handle 3810 to release the closed lock of the electrical door 20, as shown in Figure 11 (B).

[0109] Next, insert a hand wearing work gloves into the back side of the electrical door 20 from the portion opened by opening the fire extinguisher door 18 of the door opening 15 shown in Figure 3, turn the thumbscrew 3610 with your fingertips to remove it from the screw hole of the mounting piece 3620, release the internal door 32 from being closed, and perform the repair work of removing the faulty push button switch 2410 and replacing it with a new one, following the electrical door 20, as shown in Figures 5 and 10.

[0110] When the repair work is completed, the internal door 32 is returned to the closed position and secured with the thumbscrew 3610, and then the electrical door 20 is returned to the closed position and secured closed in the same manner as the inspection work of the transmitter 24.
